SAFETY ATTACHMENT FOR GAS-BURNERS.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed March 4, 1908. Serial No. 419,074.

To all whom it may concern:

Be it known that I, HERMAN J. SGHOEN, a citizen of the United States,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in SafetyAttachments for Gas-Burners, of which the following is a specification.

My invention relates to improvements in safety attachments for gasburners.

Gas cocks of burners are sometimes turned to open position throughaccident or ignorance, allowing gas to escape into rooms and cause thedeath or sickness of the occupants, an explosion or if nothing worse, awaste of gas.

My invention therefore has for its object the provision of a simple,effective, durable and inexpensive attachment for gas burners, adaptedto be attached or removed from gas burners with great facility and toprevent gas cocks from being turned to 0 en position through accident orignorance, tiiereby eliminating, to a great degree, the chances ofoccurrences of the nature above mentioned.

In the drawings :-Figure 1 is a side view of a gas burner having mysafety attachment applied thereon. Fig. 2 a vertical sectional viewtaken on the line 2-2 of Fig. 1. Fig. 3 a horizontal sectional viewtaken on the line 3-3 of Fi 1 showing the position the arm of my sa etyattachment occupies when looking the burner cock or preventing it frombeing turned to open position. Fig. 4 a horizontal sectional view takenon the same line as Fig. 3 and showing, in full lines, the position thearm of my safety attachment occupies after the burner cock has beenturned to full open position and in dotted lines the position said armoccu ies when the burner cock is turned to partia y open position, andFig. 5 a fragmentary detail view, on an enlarged scale, showing thescrew for locking the arm which locks the gas cook, said screw beingshown in full lines, in the position it occupies when looking said armand in dotted lines in the position it occupies when withdrawn to allowsaid arm to be moved to unlock the gas cock.

Like reference characters designate corresponding parts in the figuresof the drawin s illustrating my invention.

Tieferring to the drawings, 1 desi nates the body of a gas burnerwhichis secure to a service pipe and has a stop flange 2, 3 the burner cockthereof having a thumb and finger hold 4 affording means for turning itand a stop pin 5 adapted to contact with the stop flange, on one side ofthe body, when the burner cock is turned to or is in closed position.All of these parts and their operation being well known the abovereference is thought sufficient and I will now describe the constructionof my safety attachment and its operation in connection with a gasburner to pro duce the desired results above referred to.

My safety attachment embodies a support having a bottom 6 provided witha stop lug or abutment 7 extending upwardly from its forward end in theline of movement of the stop pin and adapted to be engaged thereby whenthe burner cock is turned to or is in open position, a long side 8 and ashort side 9 integrally formed with said bottom at its rear end and aportion 10 hinged at 11 to the top of the short side and formingtherewith a side of equal length to the long side, the portion 10 andthat portion of the long side opposite thereto being curved so as toclosely embrace the body 1 of gas burner and their upper ends abuttingand being provided with threaded holes which receive the shank of ascrew 12 and afford means for clamping the sides together and securingthe support on the gas burner or for allowing it to be removedtherefrom.

An arm 13 is fulcrumed on a pin 14 projecting upwardly from the rear endof the bottom 6 of the support, the forward end of said arm curvingaround one side of the burner cock 3 and the stop flange 2 in ahorizontal plane and then depending downwardly in front of the thumb andfinger hold iof the burner cock and having an enlargement 15 affordingmeans for the engagement of the thumb to move the arm laterally and thehorizontal portion of the arm having a shoulder or abutment 16 normallylocated in the path of movement of the stop pin 5 and bearing againstone side thereof when the burner cock is in closed osition andpreventing it from being turned to open position.

A screw 17 is inserted through a threaded hole in the side 9 in the sameplane with the arm 13 and its end normally located far enough therefromto allow said arm to be forced laterally to disengage its shoulder orabutment 16 from the stop pin 5 and permit the burner cock to be turnedto open position and a spiral spring 18 is supported on said screw, oneend bearing against the side 9 and the other end a ainst the arm 13, andserves to normally yieldably hold said arm in its normal inward positionwith its shoulder or abutment in engagement with the stop pin 5 andprevent the burner cock 3 from being turned to open position and yetallow the arm to be forced outwardly by the lateral pressure of thethumb against its enlargement 15 to disengage its shoulder or abutment16 from the stop pin 5 and allow the burner cock 3 to be turned to fullopen position, bringing its stop pin 5 into engagement with the stop lugor abutment 7 on the support. hen it is desired to lock the arm 13 so asto hold the burner in closed position, the screw 17 is turned until itsend comes into contact with said arm.

From the foregoing description considered in connection with theaccompanying drawings it will be readily understood, assuming the partsof my attachment to be in the position shown by full lines in Figs. 1 to4 inclusive, that the burner cock is locked in closed position and thatit can be unlocked and turned to open position by forcing the armlaterally and returned to closed position and locked by turning it inthe reverse direction, which will cause its pin 5 to ride against thearm 13 forcing it outwardly against. the action of the spring 18 andthen allowing said arm to be forced inwardly again by the spring 18 whenthe pin 5 engages the shoulder or abutment 16 and it will also beunderstood from said figures of the drawings and Fig. 5 thereof thatwhen the screw 17 is turned inwardly bringing its end against the armthat said arm will be locked.

What I claim is 1. A safety attachment for gas burners embodying asupport adapted to be secured thereon and an arm fulcrumed on said support and having an abutment normally located in the path of movement ofthe stop pin of the burner cock and preventing said burner cock frombeing turned to open position and a depending portion located adjacentsaid burner cock and affording means for forcing said arm laterally towithdraw its abutment from the path of movement of the stop pin of theburner cock and allow said burner cock to be turned to open posi tion,substantially as described.

2. A safety attachment for gas burners, embodying a support adapted tobe secured thereon, an arm fulcrumed on said support and having anabutment normally located in the path of movement of the sto pin of theburner cock and preventing said burner cock from being turned to openposition and a depending portion located adjacent said burner cock andafl'ordin means for forcing said arm laterally to Wit draw its abutmentfrom the path of movement of the stop pin of the burner cock and allowsaid burner cock to be turned to open position and means yieldablyholding said arm with its abutment in the path of movement of the stoppin of the burner cock, substantially as described.

3. A safety attachment for gas burners, embodying a support adapted tobe secured thereon, an arm fulcrumed on said support and having anabutment normally located in the path of movement of the stop pin of theburner cock and preventing said burner cock from being turned to openposition and a portion located adjacent said burner cock and affordingmeans for forcing said arm laterally to withdraw its abutment from thepath of movement of the stop pin of the burner cock and allow saidburner cock to be turned to open position means yieldably holding saidarm with its abutment in path of movement of the stop pin of the burnercock, and means for locking said arm, substantially as described.

4. A safety attachment for gas burners, embodying a support adapted tobe secured thereon and having an abutment adapted to be engaged by thestop pin of the burner cock when said burner cock is turned to openposition and an arm having an abutment normally located in the path ofmovement of the stop pin of the burner cock and preventing said burnercock from being turned to open position and a depending portion locatedadjacent said burner cock and afford ing means for forcing said armlaterally to withdraw its abutment from the path of movement of the stoppin of the burner cock and allow said burner cock to be turned to openposition, substantially as described.
